Works great, except:
1). The power key still turns off the screen. Kind of a worthless shortcut if it turns the screen off. I can't think of many applications that would benefit from being launched with the screen off. Have any recommendations?
2). There's some kind of "debounce" type problem - When you press camera+power, the shutdown script gets called a BUNCH of times - this causes whatever you want to run to get called over and over until you delete the shutdown script (while fending off the app that continues to keep popping up)
